CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is a continuation application of U.S. patent application Ser. No. 16/610,984, which claims a priority of the Chinese patent application No. 201710313871.2 filed on May 5, 2017, the entirety of above-identified applications is hereby incorporated by reference.

FIELD OF THE INVENTION

The present disclosure relates to the field of communication, and in particular, to a method for determining uplink transmission parameters and a method and device for transmitting configuration information.

BACKGROUND

In a Long Term Evolution (LTE) system, only an antenna panel and a relatively small number of antenna elements (e.g., 2, 4 elements) are considered. Uplink Sounding Reference Signal (SRS) is non-precoded and is directly mapped to a port from an element. As a result, uplink transmission is relatively simple.

In 5G New Radio (NR), however, uplink Multiple Input Multiple Output (MIMO) transmission is much more complicated than that in LTE, which is mainly due to the following reasons:

Antenna configuration becomes complicated: NR can support more Panels that may have different directional characteristics; each of the Panels supports more elements, up to 32 elements. A schematic diagram of a new User Equipment (UE) antenna is shown in FIGS. 1 a, 1 b , and 2.

Flexible precoding selections at the UE side are supported: in 4G, precoding of the UE is completely controlled by a base station, resulting in inflexible uplink transmission. If this method is still adopted, it will be difficult to use a simple codebook for uplink transmission by a user when the antenna designs at the UE side are significantly different and the antenna designs for some users are relatively complicated. Therefore, the conventional scheme can only adapt to a certain part of terminals. Thus, for some terminals with special antennas, a more flexible transmission manner is needed so that a complicated codebook design is avoided. In addition, unlike in 4G, the terminal side may perform uplink transmission based on reciprocity after having enhanced functions, the principle of which is to measure a downlink pilot to obtain an optimal downlink pilot and thus an optimal downlink receiving beam corresponding to the optimal downlink pilot, and to perform reciprocity on an uplink transmitting beam when reciprocity is established.

In addition, consideration needs to be taken as to how to design the transmission of an uplink SRS and the transmission of an uplink control channel. However, no good uplink transmission design scheme has been available yet which can adapt to a variety of complicated antenna configurations, to fully utilize the channel reciprocity, effectively reduce the pilot overhead and the physical layer signaling overhead, and have better resistance to interference.

In LTE, uplink multi-antenna transmission supports some relatively simple functions, while in 5G NR, uplink MIMO transmission is much more complicated than in LTE.

In view of the above-mentioned problem that a terminal cannot determine uplink transmission parameters in a variety of complicated antenna configurations, no effective solution has been proposed in the related art.
